Protein
Citrate/malate transporter
Organism
Bacillus subtilis (strain 168)
Function
Proton motive force-driven secondary transporter that catalyzes the uptake of both citrate and malate. Appears to be an electroneutral proton-solute symporter; the number of protons transported is equal to the valence of the transported anions. Is strictly stereoselective, translocating only the (S)-enantiomer of malate.
Similarity
Belongs to the sodium:citrate (SCF) symporter family.
